The present invention relates to geldanamycin derivatives, benzoquinone ansamycin biosynthesized by gene manipulation of Streptomyces hygroscopicus subsp. duamyceticus and the method producing them, more particularly to a geldanamycin O-carbamoyl transferase gene ( gel8 )-inactive mutant, the method producing it and geldanamycin derivatives, 4, 5-dihydro-7-0-descarbamoyl-7-hydroxy geldanamycin and 4, 5-dihydro-7-0-descarbamoyl-7-hydroxy- 17-O-demethyl geldanamycin. Since geldanamycin derivatives of the present invention suppress Hsp90 like geldanamycin, they can effectively be used for antibiotic, antifungal, antiviral, antiinflammatory and antitumor agents and an immune su ressant.
